Foxwell / Schwaben Scan tool purchased from ECS Tuning about a year or so ago. I believe this is the same as the NT510. Can do a multitude of Engine and Brake diagnostics, code clearing and resets.
Can test functions with equipment activations.
Can also perform some coding such as Injectors.
I bought this to bleed the ABS module on my Wife's e53 as it activates the ABS pump to bleed air out of the brake lines and ABS modules.
Works well with other BMW models.
$125 shipped.
